Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a structure for attaching exterior wall panels to the frame of a building.

(Prior art) Conventionally, methods for attaching concrete exterior wall panels to building structures such as frameworks include fixing connecting fittings attached to the exterior wall panel to the structure, or attaching them to the structure side. There were some connecting fittings that were used to fix exterior wall panels.

By the way, when the outer wall panel is formed by concrete molding, there is no place to attach the connecting fittings to the outer wall panel, so the connecting fittings are buried in the outer wall panel. Furthermore, since the concrete exterior wall panels are heavy, the connecting fittings have been firmly attached to the structure by welding or the like.

(Problem to be solved by the invention) However, when the connecting fittings are buried in the exterior wall panel, there are problems such as inconvenience in handling such as transportation and storage of the exterior wall panel, and the inability to change the mounting position appropriately. When attaching the connecting fittings to the structure by welding or the like, there were problems such as an increase in construction costs due to an increase in the number of man-hours.

The present invention has been developed in view of these conventional problems, and provides an external wall panel mounting structure in which a concrete external wall panel having a hollow portion inside can be easily and easily attached to a framework using mounting brackets. The purpose is to provide.

(Means for Solving the Problem) The mounting structure of the exterior wall panel of the present invention is an H-beam steel installed on a framework in which a top chord member, a bottom chord member, and left and right vertical columns formed of channel steel are combined in a rectangular shape. This is a mounting structure in which the upper end of a concrete exterior wall panel, which has a vertically penetrating hollow inside, is fixed to the upper flange of a second-story beam or roof beam consisting of a mounting bracket. It is formed by bending an elastic band plate, and has a roughly U-shaped holding part on one end into which the above-mentioned upper flange is fitted and locked, and a hanging support part on the other side that is inserted into the hollow part of the outer wall panel. A piece is formed, and this support piece is once bent in the direction of the clamping part, and the lower end is bent again in the opposite direction, and the edge of the upper flange is fitted and locked into the clamping part. The mounting bracket is fixed to a second-story beam or roof beam made of H-beam steel, and the upper end of the exterior wall panel installed along the frame is attached to this second-story beam or roof beam, and is attached to the outside of the building beyond the top flange. Insert the support piece at the other end of the mounting bracket extended into the hollow part from the top end of the outer wall panel,
Due to the elastic force of this support piece, the upper edge of the outer wall panel from the hollow part to the back is pulled and fixed toward the second floor beam or roof beam.

(Function) The clamping part of the mounting bracket is attached to the indoor end of the upper flange of the second floor beam or roof beam in correspondence with the hollow part of the outer wall panel, and the frame and the mounting bracket are fixed. Next, while elastically curving the mounting bracket upward,
Place the back of the exterior wall panel on the frame. Then, the curved state of the mounting bracket is released, and the support piece is inserted into the hollow part of the outer wall panel. Then, the exterior wall panel is sandwiched between the outdoor end of the second floor beam or roof beam and the support piece of the mounting bracket. This makes attachment of the exterior wall panels to the framework extremely simple and easy.

(Example) Hereinafter, the configuration of the present invention will be explained based on the drawings for an example.

Figures 1 to 4 show the outer wall of the building according to the present invention.
As shown in the figure, an outer wall portion 1 is made up of a plurality of outer wall panels 3 stretched over a framework 2, and windows 4 are provided at appropriate locations.

For example, as shown in FIG. 2, the frame 2 in the area enclosed by the two-dot chain line in FIG. ) The upper chord material 2a and the lower chord material 2 formed by
b. It is formed by framing vertical columns 2c, 2d, middle columns 2e, 2f, and middle beams 2g, 2h, and is fixed in an upright manner on the floor beam (not shown) of the first floor, A second floor beam or roof beam 7 is fixed on the upper end, that is, on the upper chord member 2a. The second floor beam or roof beam 7 is made of H-beam steel.

On the other hand, the exterior wall panel 3 to which the back portion 3a is attached to the framework 2 is made of concrete, and is made of not only inorganic materials but also a mixture of inorganic and organic materials, or foamed materials of these materials. A hollow portion 3b is provided therein extending in the vertical direction. The dimensions of the exterior wall panel 3 are, for example, about 50 cm in width, about 300 cm in height, and about 5 to 6 cm in thickness.
It is. As shown in FIG. 1, the outer wall panel 3 is
Four pieces are attached to one frame set 2. That is, two outer wall panels 3, 3 are attached from the vertical column 2c to the middle column 2e, and two outer wall panels 3, 3 are attached from the middle column 2f to the vertical column 2d, respectively.
The attachment relationship between the framework 2 and the exterior wall panel 3 changes depending on the shape and dimensions of the building. For example, in the area where the window 4 is installed in FIG. The vertical dimensions of the framework 2 and the outer wall panel 3 are set to be smaller than those in the previous example.

The upper flange 8 of the second floor beam or roof beam 7 has
A mounting bracket 9 is attached to support the upper edge 3c of the outer wall panel 3.

As shown in FIG. 5, the mounting bracket 9 is formed of a single elastic band plate and includes a mounting body 10 that is removably attached to the upper flange 8.
and a support piece 11 that is connected to the outdoor end of the attachment body 10 in a hanging manner, and is approximately L-shaped. As shown in FIG. 4, a substantially U-shaped gripping part 10a is formed at the indoor end of the mounting body 10 by folding the mounting body downward toward the outdoor side. The edge 8a of the holder is fitted into the holder. Further, the support piece 11 is once slightly curved inward, that is, toward the indoor side, and the lower end is bent again in the opposite direction. When inserted from above, the upper end 3 of the outer wall panel 3
c is configured to be elastically pulled toward the second floor beam or roof beam 7 side and supported.

Therefore, in order to attach the outer wall panel 3 to the framework 2 as shown in FIG.
2 to the lower chord member 2b, and attach the mounting bracket 9
The holding part 10a is attached to the indoor end of the upper flange 8 of the second floor beam or roof beam 7 in the hollow part 3 of the outer wall panel 3.
After being attached in accordance with step b, the lower edge 3d of the outer wall panel 3 is supported by the support fittings 12.

Next, while elastically bending the mounting bracket 9 upward, the back portion 3a of the outer wall panel 3 is supported by applying it to the framework 2. Finally, the curved state of the mounting bracket 9 is released, and the support piece 11 is inserted into the hollow part 3b of the outer wall panel 3 and supported. Thereafter, the required number of outer wall panels 3 are sequentially attached to the frame assembly 2 in the manner described above to assemble the outer wall portion 1.

In the above embodiment, longitudinally long grooves 13 (third
(see figure) may be formed in advance to allow ventilation in the vertical direction inside the outer wall portion 1. Further, the dimensions of the hollow portion 3b are set in consideration of the strength of the outer wall panel 3 so as to reduce the weight of the outer wall panel 3 as much as possible.

(Effects of the invention) As described in detail above, the present invention makes it possible to attach the exterior wall panel to the framework extremely simply and easily without the need for welding, and to efficiently perform the assembly work of the exterior wall. I can do it.
